title: Transgenic induction in Salmonid and Tilapia fish.
abstract: Why produce transgenic fish? There are two chief reasons for introducing novel genes into animals. The first is as a means of increasing knowledge of gene regulation in that particular group of organisms. The second is that transgenic induction may involve some economic benefit from the modified organism in terms of its increased growth potential, disease resistance, or other desirable genetic trait. Both reasons are of importance in the context of transgenic fish. Fish are good candidates for transgenic induction for several reasons. They lay large numbers of eggs, and both fertilization and development are external to the body of the female (except in a few species of mouth-brooding fish and ovoviviparous species, such as the guppy [Poecilia]). Also, the eggs are usually quite large and may be readily pierced by a suitable glass needle.
